A small thing, but the mechanistic approach to bundling packages into bigger meta state, is (in my personal opinion) better than the somewhat ad-hoc approach to both writing and including things in an apt/dpkg.

If the product is python, thats what it is. there is no python-additonal-headers or python-dev or bundle-which-happens-to-be-python-but-how-would-you-know.

There is python, and there are meta-ports which explicitly 'call' the python port.

The most notable example being X11. Its sub-parts are all very rational. fonts are fonts. libs are libs. drm is drm. drivers are drivers.

(yes, there is the port/pkg confusion. thats a bit annoying.)
